Logical operators

Operator	Function	Example	Explanation
`eq`	Equal	`[eq(<TOOL>, 0)]`	True if `<TOOL>` ≡ 0 Also works for strings.
`neq`	Not Equal	`[neq(<TOOL>, 0)]`	True if `<TOOL>` ≠ 0 Also works for strings.
`lt`	Less Than	`[lt(<TOOL>, 0)]`	True if `<TOOL>` < 0 Also works for strings.
`gt`	Greater Than	`[gt(<TOOL>, 0)]`	True if `<TOOL>` > 0 Also works for strings.
`le`	Less Than or Equal	`[le(<TOOL>, 0)]`	True if `<TOOL>` ≤0 Also works for strings.
`ge`	Greater Than or Equal	`[ge(<TOOL>, 0)]`	True if `<TOOL>` ≥ 0 Also works for strings.
`and`	And	`[and(<Z-UP>, <INDEX>)]`	True if both `<Z UP>` and `<INDEX>` are true.
`or`	Or	`[or(<Z-UP>, <INDEX>)]`	True if either `<Z UP>` or `<INDEX>` is true.
`not`	Not	`[not(<Z-CHANGED>)]`	True if `<Z CHANGE>` is false.
`apxeq`	Approximately Equal (if tolerance is not given, the default is 1e-6.)	`[apxeq(<Z-COORD>, 0)]` `[apxeq(<Z-COORD>, 0, 1e-6)]`	True if `<Z COORD>` ≡ 0 within 1e-6.

To output Z as 0 if Z is within 0.0001 of zero:

<IF>[apxeq(<Z-COORD>, 0, 0.0001)]<THEN>
  N<SEQ> G00 X<X-COORD> Y<Y-COORD> Z0<EOB>
<ENDIF>

To make Rapid Move use polar coordinates:

N<SEQ> I0 J0<EOB>
N<SEQ> G10 R[sqrt(pow(<X-COORD>, 2) +
pow(<Y-COORD>, 2))]
H[D|3.2|1.0:atan2d(<Y-COORD>, <X-COORD>)]
<EOB>

To output Z as 15 if Z is between 10 and 20 inclusively:

<IF>[and(ge(<Z-COORD>, 10), le(<Z-COORD>, 20))] <THEN>
  N<SEQ> G00 X<X-COORD> Y<Y-COORD> Z15<EOB>
<ENDIF>

If P1 variable is not set, set it to the string G0:

<IF>[eq(<P1>,"")]<THEN>
  [<P1>=”G0”]
<ENDIF>
